The Abbots Bromley Horn Dance is supposedly one of the oldest folk traditions in Europe. Some people say this is a fertility rite, others a hunting rite (that’s what I’ve heard anyway). I personally believe it to be an ancient hunting rite.
I like looking up folk customs like this because it’s just more proof that paganism didn’t die out completely, it just adapted so it could survive. Paganism will always ring true to humanity more than pure Christianity, if it didn’t, we wouldn’t have customs like this any more I believe.
